To all whom t may,l con/cern; l l. l

Be it known that'I, PAULDIGKINsoN, a' citi- ,zen of the United States,residing at Chicago,

, inlthe countyoil Cook and State of Illinois,have

invented a new' andruseful Improvement in Smoke-Stacks, ofwhich thefollowing isa specification.

f My invention relates to improvements in adjustable smoke-stacks forlocomotive roundhouses; andv my object is to providelcertainimprovementsr in the construction of such smoke-stacks and supportingmeans therefor verse sectional view taken on line 1 lof Fig.

2, viewed in the direction of the arrow, and also on aline through theshafts F and f at the right of the sectionline l` 1; Fig. 2, a brokensection, on'a reduced scale, taken on line 2 in Fig. l and viewed in thedirection or' the arrow; and Fig. 3, a broken Y sectional detail Viewtaken on linee?) in Fig.l l. i Afis the roof of a locomotive shed orroundbouse, provided with a longitudinally-'extending opening a directlyover the track on which the locomotive moves into its stall. Mountedupon the rootI at opposite sides of said open. ing are parallel framesI) e, supporting horizontallyextending rails c and guards 0l.

B is a frame of a vehicle or;support of a length preferably nearlydoublel that of the f opening a and mounted on flanged end wheels e andintermediate wheels f, all of which run upon the rails or track c. Theframe B has a'rootl g, sides h, extending nearly to the surface of theroot' A at the outerv sides of the track-frame b, and ends a e. `In theroof g is vat its lower end a limited distance in the directionlongitudinally of the frame. .Journaled in bearings on the frame B is acrossshaft C, :provided at opposite sides ot' the stack-'section n withlarge chain-sh eaves p, eX- tending tothevertical plane'otl the centerof said section. v Also uponth'e shaftC is a wormwheel p. Journaled inbrackets on the trarne B is a longitudinally-extending shaft D, runningbeneath the worm-wheel p and having af worm D', meshing with the lwheel10': y Also upon the shaft D is achain-sheave D2, carrying a looseendless chain D3.

,f- E is a lower stack-section fitting alongr its upperl end loosely ortelescoped in the section 7i and provided at its lower .end with a hoodor inverted funnel E. Chains E2 are fastened at their lower ends tothelower end or funnel v portionoi` the stack-section E at oppositesides- `the sheaves p.

The chain D3 hangs within convenient reach of an operator, and bydrawing upon the said chain'the shaft D is rotated to cause the wormtoiturn the worm-wheel p and Yshaft C to turn the sheaves p, and thusraise or lower the Astack-section E.

The supporting-wheels f for the frame B are upon a cross-extendingshaftf', which carries adjacent to the wheels f gear-wheels f2.

`Above and parallel with the shaft f is a crossextending shaft F,journaled in the frame B and carrying pinions FsF", meshing with thegear-wheels f2. On theshaft F is a chainsheave F2, carrying a hangingoperating-chain F3, which also extends downward t0 be readily reached bythe operator.` A pull vupon the chain F3 causes it to rotate the sheavef2 and shaft F, whereby the pinionsF rotate .the gears f2 and shaft f tocause the lwheels f to travel upon the track c, and thus move the frameBand the smoke-stack along the opening ct.

When a locomotive is moved into its stall,

it maybe stopped with its stack at any point between the ends of theopening a in the roof. By drawing upon the chain F3 an operator may thenmove the frame B until theifunnel c ered to the locomotive-stack. Shouldthe locomotive be moved while the section E covers the locomotive-stack,the said section E and the section n will swing upon the bearing m torelease engagement between the stacks.

While I prefer to construct my improven ments throughout as shown anddescribed, they may be variously modified in the matter of detailswithout departing from the spirit of my invention as deiined by theclaims.

What I claim as new, and desire to secure by Letters Patent, is

l. In a locomotive-shed, the combination of a roof therefor, having anopening through it, a smoke-stack support mounted to slide back andforth along said roof, and a smoke-stack on said support extendingthrough said openving and adapted to be brought into operative relationwith the stack of a locomotive.

2. In a locomotive-shed, the combination of a roof therefor having anopening through it, a smoke-stack support mounted to slide back andforth along said roof, and a smoke-stack carried by and depending belowsaid support and extending through said opening, and adapted to bebrought into operative relation with the stack of a locomotive.

3. In a locomotive-shed, the combination of a roof therefor having anopening through it, a smoke-stack support mounted to slide back andforth along said roof, and a smoke-stack carried by said support,extending through said opening and having a swinging section, dependingbelow said support, and adapted to be brought into operative relationwith the stack of a locomotive.

4. In a locomotive-shed, the combination of a roof therefor having anopening through it, a smoke-stack support mounted to slide back andforth along said roof, and a smoke-stack, carried by said support,extending through said opening and having a teleseoping sectiondepending below said support and adapted to be brought into operativerelation with the stack of a locomotive.

5. In a locomotive-shed, the combination of a roof therefor having anopening through it, a smoke-stack support closing said opening andmounted to slide back and forth along said roof, and a smoke-stackcarried by and extending through said support and adapted to be broughtinto operative relation with the stack of a locomotive.

6. In a locomotive-shed, the combination of a roof therefor having anopening through it, parallel track-rails on the roof at opposite sidesof said opening. a wheeled smolmstael support mounted to rnove back andforth upon said track over said opening, anda smokestack on said supportextending through said opening and adapted to be brought into operativerelation with the stack of a locomotive.

7. The combination of a locomotive-shed roof provided with an opening,of parallel rails on said roof at opposite sides of said opening, aninelosed vehicle of greater length than said opening mounted to move onsaid rails, and a smoke-stack mounted on said vehicle and extendingdownward through said opening, and adapted to be brought into operativerelation with the stack of a locomotive, the vehicle forming at alltimes a hood over said opening, substantially as and for the purpose setforth.
